TRX-NXT-512x512 with Dual Sync References and Single/Dual NR-33000
Figure 85.
This arrangement is similar to the one that is described on the previous
page, except that two sync references are used. The NR board in the
Primary slot will feed Sync Lines 1 and 2. If the NR is removed, Sync Lines
1 and 2 will automatically switch to the SR-33500.
Note
A secondary NR-33000 can be installed to provide Broadlinx redundancy. In
this case, the NR REF IN 3 and 4 connectors would not be used.
For a discussion concerning which of the two sync references should be
connected to the control system, see
Sync Connection to Control System
